The health care industry, amplifying Gov. Charlie Baker's stay-home-for-the-holidays message, released a joint video statement Monday. "It may be the 'most wonderful time of the year' as Andy Williams famously sang in 1963, but during the pandemic this holiday season is also the most dangerous," the Massachusetts Health & Hospital Association wrote in its weekly newsletter. "The state and the Massachusetts hospital community are urging people to limit in-person celebrations to household members only, and to postpone or cancel travel this holiday season. Stay away from Santas, deliver carols virtually, and maintain social distancing if out and about looking at holiday light displays."
